In addition, there was also no statistically significant difference in the levels of E2 (p = 0.997), progesterone (p = 0.986), testosterone (p = 0.531), FSH (p = 0.218) and LH (p = 0.103) between postmenopausal women with type 1 (n = 104) and type 2 (n = 16) endometrial cancer. Here, PLOD1 is linked to endometrial cancer.
